Abstract: 1,223,962. Preparing chlortetracycline bisulphate. DIAMOND SHAMROCK CORP. 26 Feb., 1969 [28 Feb., 1968], No. 10388/69. Heading C2A. Crystalline chlortetracycline bisulphate is prepared by slurrying chlortetracycline in tetrahydrofuran, adding sulphuric acid to the slurry to form a solution of the bisulphate, clarifying the solution, and crystallizing and recovering the required product. The sulphuric acid may be added as a mixture with further tetrahydrofuran. Crystallization may be initiated by seeding with crystals of chlortetracycline bisulphate or by addition of a non- solvent, e.g. C 1  to C 4  alkanols. The starting tetracycline is suitably prepared by treating the hydrochloride salt with alkali or nitrogenous base. A further yield of the bisulphate is obtained from the mother-liquor after crystallization by precipitation with a non- solvent.

Title: Improvements in automatic bobbin changing mechanism in looms
IPC: D03D45/20
Filed: 1963-03-19
Abstract: In a loom having change boxes at both ends, a fresh bobbin released from the magazine drops into a cradle which supports it above the beat-up position of the slay.  The depleted shuttle is received in an extra top cell of the change box when replenishment is initiated and is lifted above race level at the next beat-up to receive the fresh bobbin, which is either held stationary by pads fixed on the slay coming over it or is depressed to meet the shuttle by pads pivoted on the slay.  The cradle consists of fingers which either yield or are retracted to allow the bobbin to enter the shuttle.  The depleted bobbin is ejected through a hopper situated between the extra cell and the normal cells of the box.  Weaving is interrupted during replenishment by stopping the dobby for two picks or by turning it backwards on the first pick and allowing it to turn forwards again on the second pick.

Title: Remote-control electrical apparatus for positioning a load
IPC: G05D3/14
Filed: 1956-04-09
Abstract: 799,056. Control of several motors; controllers. NOVEL PRODUCTS CORPORATION. April 9, 1956 [Jan. 5, 1956], No. 10795/56. Class 38 (3). The tuning of a radio receiver 112 is changed clockwise from one setting to another by placing a change-over switch 114 in its right-hand position. An electric motor 110A, driving an indicator 115, and an electric motor 110B which drives the load 112, are both energized and both rotate in the clockwise direction. The motor 110A turns slightly faster than the motor 110B, so that contacts 118A, 119A, are opened by the disc 116A before contacts 118B, 119B, are closed by the disc 116B, and the motor 110A is deenergized to remove a slight residual deviation between the position of the load and that of the indicator. When the contacts 118B, 119B are closed the motor 110A is re-started with a slight lag since the energizing circuit for the motor 110B is independent of either the contacts 118A, 119A, or 118B, 119B. The motor 110A remains operated so long as the closure periods of the two sets of contacts continue to overlap. As the motor 110A eliminates the lag and then takes the lead over the motor 110B, this overlap is removed and the motor 110A is again de-energized until the motor 110B regains the lead, whereupon the motor 110A is restarted. Operation in this manner continues until the desired position of the indicator 115 has been reached and the switch 114 is opened to stop both motors. Had it been desired to move the indicator-needle counterclockwise, then the switch 114 would have been moved to its lefthand position for appropriate rotation of the two motors. In another arrangement, when a pointer 215 is moved from one set position to another, a brush 227 engages strip 225<SP>11</SP> to energize indicating lamp 235. Brush 229 engages strip 226<SP>11</SP> to energize conductor 221 from transformer 230. Field windings 233<SP>11</SP>, 234<SP>11</SP>, of motors 210A, 210B, are thus excited, the circuit for the winding 233<SP>11</SP> being completed through disc 216A and wiper 218A. The alternate opening and closing of contacts 217A, 218A and 217B, 218B operates in the manner described to energize the motors until the disc 214 arrives at the preselected position, whereupon brush 229 disengages from strip 226<SP>11</SP> and the lead 221 is de-energized. Lamp 235 is disconnected to signal that the system has come to rest. In another embodiment, three motors are interconnected in a cascade arrangement, each leading motor driving one or more discs for controlling a following motor or motors. The motor at the controller stage may be comparatively small and of low inertia, a somewhat heavier unit being used at the intermediate stage, and a still more powerful motor coupled to the load at the final stage, Fig. 3 (not shown).

[Class 42 (i).] Designs, producing.-Special moirÚ effects are produced on a long length of fabric, folded longitudinally on itself, by a pressing member which moves across the fabric in the direction of the weft. The fabric passes from a roll c between two heated pressure-rolls a, b arranged parallel to its direction of feed and is rewound on a roll d. The forward feed is intermittent and during the periods of rest the rolls c, d are moved axially and the rolls a, b correspondingly rotated so that the material situated between the pressure rolls has a moire effect produced thereon. During the return movement of the rolls c, d, the rolls a, b may be separated or given a reverse rotation so as to impart a second pressing to the piece of material being operated on. The fabric is then fed forward a distance slightly less than the length of the rolls a, b and the operation is repeated. The rolls c, d may be fixed and the rolls a, b given a transverse movement across the fabric. In a modification of the latter form, either of the rolls a, b may be replaced by a flat plate.

Abstract: 1350821 Modulating light THOMSON-CSF 23 April 1971 [24 April 1970] 11166/71 Heading H4F [Also in Division G5] In a display system, one surface of a birefringent block 1 is provided with a reflective electrode 5 forming a common part of a plurality of selectively operable electro-acoustic transducers 6, 7, each transducer being capable of passing an acoustic beam through a respective volume 11 of the block in a direction normal to the electrode 5, and an upper surface opposite electrode 5 lies in a plane at an angle # thereto so that a plane polarised collimated laser beam 2 incident thereon is refracted thereby so as to be incident normally on the electrode 5. With no transducer activated the light is reflected out of the body and back to the source, but with an acoustic beam present in a volume 11 the light beam in that volume is collinearly diffracted, to produce a beam with a different plane of polarization, e.g. normal to that of the incident wave, and with a wave number #k d  = #k i   #k where #k l  and k are the wave numbers of the incident optical and acoustic beams, which is refracted by the upper surface to pass in the direction 4. Thus by actuating selected transducers, a pattern, e.g. numeral or letter, may be observed from direction 4. The shape of the upper surface of the block also prevents reflection of the acoustic beam back to electrode 5. In modifications, the diffracted beam is internally reflected at the upper surface and leaves from the side of the block, e.g. by making # equal to the Brewster angle # for the incident polarized light beam, Fig. 2 (not shown), or by arranging for the input beam to be at grazing incidence on an appropriately inclined upper surface, Fig. 3 (not shown). The block 1 and transducer material 6 may both be of quartz and an acoustic absorbing layer is provided in the embodiment of Fig. 3.
